Dreamed the frost line was a fence I kept hopping

I'm walking the north edge of the field at 4am and the frost line has become a low wire fence. I keep hopping it, but every time I land, the soil is warmer and the crops are further ahead — tomatoes already fruiting in one jump, squash rotting in the next. My boots are wet the whole time, which is the part that stuck with me. This morning the real frost was light, so maybe that fence was just telling me something about how I keep rushing the season.
